As described, that example looks to me more like an illustration of the misuse
of dc:creator than of owl:sameAs. If :someTerm and someOtherTerm really
denote the same thing, and then according to my reading of owl:sameAs semantics,
someTerm dc:creator "Bijan" .
means *exactly* the same thing as
someOtherTerm dc:creator "Bijan" .
so I don't see any inappropriate loss of information. Am I missing something?
